When installing Java (Latest version), to our new SBS 2003 / Windows XP SP2 Environment, the internet explorer developer toolbar does not start anymore, instead it opens a Java console. (It does so even when i set within the java settings to never run the console).

When I uninstall Java IE Developer Toolbar works fine again,

When first installing java and then the Toolbar, results into the same effect.

Have you tried giving a normal user temporary full access to the C:\Program Files\Internet Explorer folder?
Or - if that doesn't work - how about giving them temporary full access to the java directory?
( C:\Program Files\Java )

There must be an issue between the version of java the toolbar uses - and the installed JRE.
Does the toolbar function in another browser - i.e. Firefox?
If it can run in there (or a alternative version) - then possibly the issue is to do with IE...

Well i've inserted a ticket @ the microsoft forums too, so if i find anything there, i will return the result here.

BTW are there any alternatives? toolbars that run within Internet Explorer? because yeah we've also got firefox, but everything
must be developed in IE first, firefox second. So thats why we use the IE toolbar.

Yes he helped me trying to figure it out, But its not a solution, because the problem still has not been solved.
Thats why i did not close the topic yet.

If you would accept his answer, it would result into having a wrongly answered question within the database on which users will think that it has been solved and all they see is that its a problem between java and the toolbar, which i already stated at the beginning of the question.

Its not that i don't want to give him points, because if a solution comes up, he would atleast get assisted. But thats all because its not the solution to my question.
